The IMARS system, utilising Cobham's inertia reel technology,
enables aircrew members to complete a full range of required
mission tasks by allowing freedom of movement and full access
throughout the aft cabin and the ramp area. As an evolution
of Cobham Life Support's Mobile Aircrew Restraint System (MARS),
the Integrated Mobile Aircrew System (IMARS), originally designed
for the CH-53K, interfaces directly with the airframe and consists
of a "track and trolley" system. This mobile inertia reel can
be fixed to multiple set positions along the track, allowing for
greater range of mobility throughout larger airframe cabins.
During a crash event or hard landing, the inertia reel locks the
webbing in place enhancing occupant survivability.
Key features of the IMARS include:
- Allows for greater movement throughout the entire aft cabin and
ramp area
- Prevents occupant ejection from the aircraft
- Reduces the likelihood of injury due to contact with interior
surfaces
- Restrains crew, limits motion and displacement during
survivable aircraft crashes or hard landings
- Automatically locks within one inch of webbing
